Maintenance and Troubleshooting

Identifying the Left and Right Polarizers: Although the left and right polarizers have very different optical characteristics, they appear to be identical. As a result, once you remove them from the projector it may be difficult to tell them apart. Use the following technique to verify which one is which:

1.Place the polarizer on a clean, smooth, flat surface with the side that faces the projector facing up.

2.Hold a pair of 3D glasses above the polarizer as shown here:

3.If the right lens on the glasses turns black when it is above the polarizer, this tells you that the polarizer came from the left-eye optical engine on the projector.

Troubleshooting Table 5-1provides some general guidelines for troubleshooting problems you may encounter with the D-73d Series LED 3-D Home Theater Projection System.
